About Course

The course is designed with the simple phrase in mind: “Prevention is Better than Cure”. The course provides a comprehensive understanding of three stuck pipe mechanisms, causes leading to each mechanism, and recognition of warning signs. Participants will learn how to perform the trend analysis and learn to “listen to the well” by understanding the “language of the well”.

The course includes a stuck pipe mechanism identification table and recommends the first actions for each mechanism. Stuck pipe case histories are included to enhance the learning. The course also covers knowledge of the formations and borehole instability problems and recommends guidelines to empower the driller on best tripping practices. We recommended that the course is taken by the rig team together, as a team building exercise as well as an opportunity to improve communication skills.

This operations-oriented training emphasizes a proactive approach to stuck pipe prevention. It teaches how to “listen to the well” and perform trend analysis. The course also focuses on how to detect the causes leading to stuck pipe at an early stage and what preventive actions to take before full sticking occurs.

What will this course cover?

The course emphasizes the importance of recognizing the signs at an early stage and taking PREVENTIVE actions before the sticking takes place. It is designed to increase the knowledge and competency of the drilling crews. It empowers the drilling crew to perform correct diagnosis, improve communication, and take the correct “First Actions” to prevent stuck pipe incidents. Studies have shown that about 90% of stuck pipe incidents can be freed with appropriate “First Actions” within the first 4 hours of sticking. The course also includes the effective use of drilling jars and understanding of pump open force.
